Question 4948 Deck General
70% to passWhat is the change in longitudinal moments for the Coastal Driller if 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 1?
A
15,565 foot-kips increase
B
7,585 foot-kips increase
C
16,041 foot-kips decrease
D
15,565 foot-kips decrease
AI Explanation
The correct answer is D) 15,565 foot-kips decrease. When 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 1, the longitudinal moment will decrease by 15,565 foot-kips. This is because moving the weight from a position further aft to a position further forward on the vessel will reduce the overall longitudinal moment, causing a decrease. The other options are incorrect because they do not accurately reflect the change in longitudinal moment resulting from this specific tank transfer scenario. A decrease in longitudinal moment is the proper response, not an increase.
